6. Difficulties defining LIS “The question, ‘What is library and information science?’ does not elicit responses লུ A multidisciplinary, interdisciplinary or monodisciplinary field? The Swedish researcher Emin Tengström (1993) [11] described cross-disciplinary research as a process, not a state or structure. লུ A more recent study revealed that 31% of the papers published in 31 LIS journals from 2007 through 2012 were by authors in academic departments of library and information science লུ , and the other natural sciences (7%) were also represented. Nearly one-quarter of the papers in the 31 journals were by practicing librarians, and 6% were by others in non-academic (e.g., corporate) positions.[13] References 1. Bates, M.J. and Maack, M.N.
